24/7 Biohazard and Crime Scene Cleanup in Hornsby, TN

Hornsby is an incorporated town that lies mainly in Hardeman County but extends east into neighboring McNairy County, a county span the dataset's record does not show.

The town stands on U.S. Highway 64 just east of Bolivar, the Hardeman County seat, in southwestern Tennessee.

Before 1820, Dr. Daniel Smith Webb built a gristmill and sawmill on the Little Hatchie River in Wade Creek Valley, and the settlement that grew up around Webb's Mill became known as Crainville, a stagecoach stop and supply depot with churches, a school, and an inn between Bolivar and Purdy.

Crainville became a railroad town in the early 1900s when the Gulf, Mobile and Northern Railroad built a depot on land owned by Kimborough Hornsby, and the new town took his name.

Hornsby's municipal charter was written on October 16, 1920, when its first town government was formed.

An artesian well drilled near the depot in 1915 was said to be the first of its kind in the United States, and by 1923 the town had nine such wells and was known as "the village of artesian wells."

One of Hornsby's original artesian wells, more than a century old, remains open to visitors on the grounds of Hornsby Elementary School, the town's only school.

A tornado struck Hornsby in 1971, destroying a number of homes, though many of its early-20th-century houses still stand and traces of old Crainville remain visible east of town.

The 2020 census counted 264 residents in Hornsby, down from 303 in 2010.

The 2000 census counted 123 households in the town, with an average household size of 2.49 people.
